The ubiquity of the cell phone camera means that every moment in our lives is photographable. One consequence of this is an altered perception of the gravity of our day-to-day routines. We are now more aware of ourselves as observers of “history.” When a van catches fire in front of our house, we and our neighbors are now out on the lawn recording. We e-mail this to our friends, who testify to the enormity of the event, and then we all await the next sensation. This impulse can be positive, but it also fuels the increasingly destructive American habit of oversharing. The snapshot speaks with a small voice: I’m alive and I saw this. The cell phone camera picture or video is a shout from the rooftop: Check out this crazy thing that happened to me. —Michael Agger —The Camera Phone: The Gadget that Perverts, Vigilantes, and Celebrity Stalkers Can All Agree On (Slate)
